Prepare coffee and cocoa. Divide the hot coffee and cocoa between two mugs or heat proof glasses. Add an ounce of vodka and an ounce of kahlua to each drink. Stir to combine and top generously with marshmallows and a sprinkling of cocoa powder. Enjoy!
Notes
I love these Bodum tumblers both for how pretty they are and their ability to hold both hot and cold drinks. However, any mug or cup that can handle a hot drink will work perfectly for this cocktail. That said, this might not be the perfect time to use that travel coffee cup; this is most definitely not a coffee or cocoa for the road.
